The light beam of the lighthouse pierces the folds of time, and the tower keeper Lin Yu salvages the drowned past in the echo of the abyss. The cracks in the time abyss left by her father seeped out the ghosts of the past and the echoes of the future. She navigated the gap between reality and dreams, searching for the truth swallowed by time among the reefs of lost memories and the whispers of obsessed dead souls. When the whispers of the abyss gradually turn into madness, she must make a choice: become a monument to seal the rift, or ignite herself and become the anchor of dreams that illuminates all lost paths.
